B&B Electronics FOSTCDRI

Industrial Serial to Multi-mode Fiber Converter Any two pieces of asynchronous serial equipment can communicate at half or full duplex over two fibers at rates up to 460 kbps for RS-422/485 or 115.2 kbps for RS-232 with a pair of these converters. Fiber lines are inherently resistant to EMI/RFI and transient surges, so they are ideal for data communications near heavy electrical equipment and other electrical or radio interference.

Standards can be mixed and matched so RS-232 devices can be connected to RS-422/485 devices, replacing a converter and isolator. When working with RS-485 signals, B&B Electronics’ Automatic Send Data control eliminates the need for driver software. Serial connections are on terminal blocks; multimode fiber side has two ST connectors. Requires external power supply not included.

This model is configured so that the fiber optic transmit light is ON in the idle state. If you require the transmitter light to be OFF in the idle state, order model number FOSTCDRI-INV.
